, Be it known that I, JOSEPH REN irocrrn, a subject of the King of Great Britaim'residing; at Chicago, in the county oyCook and State of Illinois, new' and useful Improvements in Wrenches,

i, of which the vfollowing is a specification. Y.

This invention relates to improvements in wrenches.

One of the @mais "of simplify and reduce `the' cost of devicesof' thecharacter of wrench pending application Serial No. $1,162; tiled November 10, 1921.

have invented certain an angular thek invention is to detailed `construction and to described in `my co-` Q fiippiieatidnmea :December 2,1921.; sensi-iro. 519,332.

member within 'thel p' a r 1, andthereby"v clutch member 15-`ar`1`d"thotherind o the member 21 `is rotatable when the shaft or rod 13 is rotated." In like manner the clutch 75 member 16-'at' the other end of the Vmember 21 is rotatable when .the rod 13 is rotated;v The clutch member16of the attachment .-21 in Fig. 3 will `engage the clutch member 15 on the upper lend of the structure shown in Fig. 1, andmember 16 of the handle 27 may engage member 15 of the attachment 21 to rotate shaft 13,0r the member 15 of the at! tachment 21 may engage clutch member 16 of Fig. land the part 211 will engagejacket 10. The holding device 19 is'providedwith a snap ring 25 which engages the notch 26 f and yieldingly holds the clutch member 15 vwithin the clutch member 16. Theinner Other-objects andy advantages of the inventionwill readilyappear Jfrom a consideration of the ollowingdes'cription when taken in conjunction with the drawings,

Fig.` 1 is a central longitudinal sectionl of the body of the wrench.

Fig. 2 is a similar view of the handle Jfor rigid attachment to the internal'rotatable shaft.

Fig. 3 is a similar view of an attachment to the body part shown in Fig. 1.

Fig'. 4 is a bottom, end vview* of the body shown in Fig. 1, and of the handle shown in Fig. 2.

Fig. 5 is a central vertical section of a clutch holding member. v l

Fig. 6 is an end view of the same.

In all the views the same reference characters are lemployed to indicate similar corresponding with the angular outer sur- Jface of the clutch member 15 lso that the two may be rotated together. T y

,The two clutch members 15 and 16 ofthe device shown in Fig. 3 are rotatably con- 95 nected by a universaljoint 26. f The handle 27 is for rigid connectionywith the `clutchin'ember 15 on the structure 'shown in Fig. 1 or inFig 3. Thehandle is transversely `perforated or `the rod 28 and a 100 plunger 29 is yieldingly rheld against thev v inner surface of the rod 28 by the open helical spring 30. A .screw 31 permits limited axial movement of the plunger 29 to frictionally hold the rod 28 in 'place with respectl 105 to the handle 27. I.

A socket 32 is a part of the clutch member 15, more clearly shown in Fig. 3, and may be used Ji'or rotating nuts having angular surfaces, such as hexagon o r square screw threaded nuts,`cap screws, bolts, and thelikelv `While parts of thestructure herein shown parts. v Y

In the illustrated device 10 is a non-rotatable, tubular, straight jacket having a per-.f forato closure 11 with a shoulder 12 against The closure 11 may be xed to the jacket 10 or rotatable with A central shaft, preferably a rod, 13, passes thruthe closure 11 and is provided with an angular head 14 to receive a clutch member 15. A. cooperating clutch member 16 is attached to the other end of the shaft, or rod 13, by a pin 17 and rotates with the rod, and with respect to the jacket or tube 10. Clutch-member 16 is also provided with a shoulder 18, so that when the clutch members 15 and 16 are secured to the respective ends of the rod, the latter is thereby conned within the jacket 10.

The general Jform and arrangement of the clutch members are similar to those shown in. my aforesaid copending `application, in

surface of the clutch member 16 is angular 90 and deserileel resemble partssof:v the structure disclosed in my prior application, 1n which they are specifically claimed therein, there are other featureslintha presentfin* 5 vention cooperating With said devices which c form the subject matter for the appended claims.
